Definitions
- the present invention relates to a joint connector.
- Japanese Unexamined Patent Publication No. 2003-59598 discloses a joint connector in which a plurality of joint terminals are provided in a relay housing.
- a joint terminal is composed of a base and a plurality of tab pieces projecting from different positions on the base. One end part of each tab piece is accommodated in a receptacle-like electrical component-side connector connecting portion, and the other end part thereof is accommodated in a receptacle-like power supply-side connector connecting portion.
- any one of a plurality of female terminal fittings provided in an electrical component-side connector and any one of a plurality of female terminal fittings provided in a power supply-side connector are connected to be possibly shorted via one joint terminal.
- the shape of the bases has to be complicated to avoid the mutual interference of the bases if two pairs of the female terminal fittings desired to be shorted are arranged, for example, on two diagonals intersecting each other.
- the present invention was completed on the basis of the above situation and aims to simplify the shape of a short-circuit means.
- the invention is directed to a joint connector with a housing.
- Terminal fittings are provided in the housing and each is formed such that tabs are coupled by a terminal base, and a short-circuit module provided in the housing and are formed by arranging short-circuit members side by side in a length direction of the tabs.
- Each short-circuit member is formed with conduction holes for allowing the tabs to pass therethrough in a contact state and a non-contact hole for allowing the tab to pass therethrough in a non-contact state.
- An arrangement of the conduction holes is different among the of short-circuit members.
- the tabs can be conductive with each other via one short-circuit member. If mating terminals are connected to the tabs, the mating terminals connected to the tabs in a conductive state can be shorted to each other. Since the short-circuit members for making the tabs conductive with each other are arranged side by side in the length direction of the tabs, the short-circuit members do not interfere with each other. Thus, the shapes of the short-circuit members can be simplified.
- the conduction hole may be formed with a resilient contact piece projecting inward from an edge part of the conduction hole and is capable of resiliently contacting the tab. According to this configuration, since the resilient contact piece is resiliently deformed when the tab passes through the conduction hole, resistance can be small.
- the short-circuit members may be laminated via an insulating member. According to this configuration, a short circuit between the short-circuit members can be prevented.
- the insulating member may be formed with a guide hole corresponding to the non-contact hole and may have a smaller opening region than the non-contact hole. According to this configuration, the contact of the tab with an edge of the non-contact contact hole can be prevented.
- the insulating member and the short-circuit members of certain embodiments can be assembled. According to this configuration, if one short-circuit unit is configured by assembling the insulating member and the short-circuit members, the short-circuit members and the insulating member are handled easily.
- the short-circuit members and the insulating member may be formed with erroneous assembly preventing portions fittable only when the short-circuit members and the insulating member are assembled properly. According to this configuration, the short-circuit members and the insulating member cannot be assembled improperly.

- each short-circuit unit 41 is a common component, but one of a plurality of different types of the short-circuit plates 42 is used for each short-circuit unit 41 . As shown in FIGS. 15 to 17 , each short-circuit unit 41 is different from the other short-circuit plates 42 in the arrangement and number of the conduction holes 45 and the arrangement and number of the non-contact holes 44 . That is, one short-circuit module 40 is formed such different types of the short-circuit plates 42 are laminated via the insulating plates 47 , in other words, such that a plurality of short-circuit plates 42 and a plurality of insulating plates 47 are alternately laminated.
- three short-circuit modules 40 are mounted in the body 11 while being individually accommodated in the accommodating portions 14 of the respective divided bodies 13 and held in contact with the separation walls 15 .

- the forward facing tabs 37 F passed through the conduction holes 45 of the respective short-circuit plates 42 are in a state capable of shorting to each other via the short-circuit plates 42 .
- the forward facing tabs 37 F passed through the non-contact holes 44 are not conductive with the short-circuit plates 42 formed with those non-contact holes 44 . Since the forward facing tabs 37 F are passed through the plurality of short-circuit plates 42 having different arrangements of the conduction holes 45 , as many short-circuit patterns of the forward facing tabs 37 F as the short-circuit plates 42 constituting one short-circuit module 40 can be set.

- the tabs 37 F, 37 D, 37 R can be conductive with each other via one short-circuit plate 42 .

Since the short-circuit plates 42 for making the tabs 37 F, 37 D, 37 R conductive with each other are arranged side by side in the length direction of the tabs 37 F, 37 D, 37 R, the short-circuit plates 42 do not interfere with each other. Thus, the shapes of the short-circuit plates 42 can be simplified.
- the short-circuit plate 42 is in the form of a thin plate, and the conductive hole 45 is formed with the resilient contact pieces 46 projecting inward from a hole edge part of the conductive hole 45 and capable of resiliently contacting the tab 37 F, 37 D, 37 R.
- the plate-like resilient contact pieces 46 contact the tab 37 F, 37 D, 37 R while being resiliently deformed to be curved.
- resistance when the tab 37 F, 37 D, 37 R is inserted is reduced.
- the short-circuit plates 42 are laminated via the insulating plates 47 , a short circuit between the short-circuit plates 42 can be prevented. In this way, an inadvertent short circuit between the tabs 37 F, 37 D, 37 R can be avoided. Furthermore, since the insulating plate 47 is formed with the guide holes 52 corresponding to the non-contact holes 44 and having a smaller opening region than the non-contact holes 44 , the contact of the tabs 37 F, 37 D, 37 R with the hole edge parts of the non-contact holes 44 is prevented. In this way, an inadvertent short circuit between the tabs 37 F, 37 D, 37 R can be avoided.
- the insulating plates 47 and the short-circuit plates 42 can be assembled and one short-circuit unit 41 is configured by assembling the short-circuit plate 42 and the insulating plate 47 .
- the short-circuit plates 42 and the insulating plates 47 are easily handled.
- the short-circuit plate 42 and the insulating plate 47 are formed with the erroneous assembly preventing projection 49 and the erroneous assembly preventing recess 43 fittable only when the short-circuit plate 42 and the insulating plate 47 are properly assembled, it can be prevented that the short-circuit plate 42 and the insulating plate 47 are improperly assembled.
- a plurality of short-circuit members are laminated via the insulating plates (insulating members) in the above embodiment, a plurality of short-circuit members may be arranged while being spaced apart.
- the insulating plate (insulating member) is formed with the guide holes corresponding to the non-contact holes and having a smaller opening region than the non-contact holes in the above embodiment, the insulating plate may not include such guide holes.
